Abstract
U sklopu ovog magistarskog rada obrađeni su i klasificirani mogući izvori izobličenja i interferencije kod prijenosa signala u cjelokupnoj stazi Zemlja-satelit-Zemlja. Izobličenja i interferencija su se promatrale kao rezultat utjecaja sklopovlja te frekvencijske konstelacije kanala. Da bi se dala saokružena cjelina dan je utjecaj medija kroz koji se širi elektromagnetski val na izobličenja prvenstveno gledajući na zakret polarizacije uslijed kiše. Kao osnovni izvor izobličenja u sklopovlju su svakako pojačala sa svojim nelinearnim karakteristikama obzirom da rade često vrlo blizu točke zasićenja obzirom na potrebu što boljeg iskorištenja. Kao primjer širokopojasnog, nelinearnog pojačala posebno je obrađeno pojačalo sa cijevi s putujućim valom (TWTA). U današnjim komunikacijama se koristi skoro isključivo digitalni signal pa je posebna pažnja posvećena filtriranju digitalnog signala koje pak često puta može izazvati intersimbolnu intereferenciju (ISI).
Abstract (english)
In this master’s thesis possible sources of distortion and interference on the radio signal path from Earth to satellite and back to Earth are elaborated and classified. Distortion and interference were observed as a result of the facilities and channel frequency constelation. The influence of media on the distortion which electromagnetic wave spreads around was here given with an accent on the switch of the polarisation due to influence of rain. The amplifiers with non-linear characteristic are primary source of distortion inside facilities, regarding the fact that nominal usage is often near the saturation point to get maximum utilisation. As an example of broadband non-linear amplifier, traveling wave tube was particularly elaborated. Digital signal is almost exclusively used in modern communication with special attention to the filtering of the digital signal. Filtering of the digital signal often provokes inter-symbol interference (ISI).
